[JASS] Transferring data in structs

[Diehard@Azeroth]

How can i transfer data from one struct to another? for example, a unit channels an ability, i save a timer in struct A, and in struct B extends struct A, i call dat.destroy(), but i want the timer from struct A to be destroyed? how can i get its reference? does it have to be CS, hashtables or whatnot or can this be done in structs too? (im pretty sure its can, im just bad at OOP and JASS)

 

[Element of Water]

struct A
    timer tim
endstruct

struct B extends A
    method onDestroy takes nothing returns nothing
        call DestroyTimer(.tim)
    endmethod
endstruct

This works.

thanks for that man, but how to get it based on the data reference of the unit?

child structs have access to all (non private) variables and methods of its parent so if B is really a child of A theres no need to "transfer" anything as you just could do B.unit when unit is a variable of A

and btw when you call B.destroy() and B extends A both B.onDestroy() and A.onDestroy() get called (in that order)

so lets say there is triggernig unit who stopped the channeling, how would we load the data based on the unit, do we have to do a loop to so what unit that unit is, or can we use any other method? like TriggeringUnits = GetTriggerUnit() for each loop and if/then ... you know the rest.

oh you mean attachments well just use Vexorians Table for that
something like the following should work

scope Bla initializer init
    globals
        private HandleTable UnitTable
    endglobals

    function Attach takes unit u, #struct# s returns nothing
        set UnitTable[u] = integer(s)
    endfunction

    function GetAttached takes unit u returns #struct#
        return #struct#(UnitTable[u])
    endfunction

    private function init takes nothing returns nothing
        set UnitTable = HandleTable.create()
    endfunction
endscope

o/c you would have to replace #struct# by your struct name

thanks man +rep, eh so its hashtable X_X

i think il stick to loop since max il have will be 12 so loop will never be that large, just need to use some algorythsm to get most efficient max loop, thanks again bro ^^
